Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A communication managing method, comprising: when an authentication of a user terminal is passed or user information of the user terminal is changed, an Authentication Authorization Accounting AAA server sending the user information of the user terminal to a service control server corresponding to the user terminal, wherein the user information comprises authorization information of the user terminal; the service control server performing policy control on a service of the user terminal according to the user information; wherein the authentication of the user terminal comprises: the user terminal completing the authentication with the AAA server through an authentication server; or the user terminal completing the authentication with the AAA server through an operator; wherein the user terminal completing the authentication with the AAA server through an authentication server comprises: the authentication server determining an association relationship with the service control server; the user terminal associating to the authentication server, the authentication server determining a corresponding service control server for the user terminal; the user terminal completing authentication by interacting with the AAA server through the authentication server; during the authentication, the authentication server sending information of the service control server determined for the user terminal to the AAA server; wherein the communication managing method further comprises: when the user terminal is offline, the AAA server sending a user offline instruction to the service control server; the service control server terminating the policy control on the service of the user terminal after receiving the user offline instruction.
A communication management method handles user authentication and information changes. When a user terminal authenticates successfully or its information changes, an AAA server sends the user's information (including authorization details) to the relevant service control server. This server then enforces policies on the user's service based on this information. User authentication can occur directly with the AAA server via an authentication server or through an operator. If using an authentication server, this server determines its association with the service control server and sends service control server information to the AAA server during authentication. When a user terminal goes offline, the AAA server informs the service control server, which then stops enforcing policies for that user.
2. The communication managing method according to claim 1 , wherein the authorization information of the user terminal comprises address information and/or identification information and/or service policy information of the user terminal.
The communication management method as previously described utilizes user terminal authorization information that includes the terminal's address, identification, and/or service policy details. This information is sent from the AAA server to the service control server after successful authentication or when user information changes, enabling the service control server to implement appropriate policies.
3. The communication managing method according to claim 1 , wherein the service control server performing policy control on a service of the user terminal according to the user information comprises: the service control server issuing a user forwarding information table of the user terminal to a forwarding plane corresponding to the service control server according to the user information; wherein the service control server terminating the policy control on the service of the user terminal according to the user information comprises: the service control server deleting the user forwarding information table of the user terminal in the forwarding plane corresponding to the service control server.
In the communication management method as previously described, the service control server manages policy control by issuing a user forwarding information table to a corresponding forwarding plane based on the user's information received from the AAA server. When a user goes offline, the service control server terminates policy control by deleting the user's forwarding information table from the same forwarding plane. The forwarding plane is thus updated to reflect the current state of user services.
4. The communication managing method according to claim 1 , wherein the method further comprises: after performing the policy control on the service of the user terminal according to the user information, the service control server sending a charging start instruction to the AAA server; after receiving the user offline instruction, the service control server sending a charging stop instruction.
Following the enforcement of policy control on a user terminal's service, according to the method as described in claim 1, the service control server sends a charging start instruction to the AAA server to initiate billing. Conversely, when the user terminal goes offline and the service control server receives the user offline instruction from the AAA server, it sends a charging stop instruction to the AAA server, thus ending the billing cycle.
5. The communication managing method according to claim 1 , wherein when the user terminal completes the authentication with the AAA server through the operator, the AAA server obtains information of the service control server corresponding to the user terminal from the operator.
In the communication management method as previously described, if the user terminal authenticates via an operator rather than an authentication server, the AAA server obtains the necessary service control server information corresponding to the user terminal directly from that operator. This allows the AAA server to forward user information for policy control.
6. The communication managing method according to claim 1 , wherein the managing method further comprises: when the authentication server has detected that the user information of the user terminal is changed, the authentication server sending a user information change notification message to the AAA server; or the AAA server receiving a user information change notification message sent by the operator.
The communication management method as previously described also handles user information changes. If the authentication server detects a change in a user terminal's information, it sends a user information change notification to the AAA server. Alternatively, the AAA server can receive a similar notification directly from the operator, enabling the system to update policies based on the altered user details.
7. The communication managing method according to claim 1 , wherein the managing method further comprises: when the authentication server has detected that the user terminal is offline, the authentication server sending a user offline notification message to the AAA server.
In the communication management method as previously described, when the authentication server detects that a user terminal has gone offline, it sends a user offline notification message to the AAA server. This triggers the AAA server to send a user offline instruction to the service control server, which in turn terminates policy control for that user.
8. A communication system, wherein the communication system comprises a user terminal, a service control server and an Authentication Authorization Accounting AAA server; the AAA server is configured to, when an authentication of the user terminal is passed or user information of the user terminal is changed, send the user information of the user terminal to a service control server corresponding to the user terminal, wherein the user information comprises authorization information of the user terminal; the service control server is configured to perform policy control on a service of the user terminal according to the user information; wherein the communication system further comprises an authentication server, the user terminal is configured to complete the authentication with the AAA server through the authentication server; or the user terminal is configured to complete the authentication with the AAA server through an operator; wherein user terminal comprising a hardware processor and a non-transitory computer readable medium with processor executable instructions and being configured to complete the authentication with the AAA server through the authentication server comprises: the authentication server determining an association relationship with the service control server; the user terminal associating to the authentication server, the authentication server determining a corresponding service control server for the user terminal; the user terminal completing authentication by interacting with the AAA server through the authentication server; during the authentication, the authentication server sending information of the service control server determined for the user terminal to the AAA server; the AAA server is further configured to, when the user terminal is offline, send a user offline instruction to the service control server; the service control server is further configured to, after the user offline instruction is received, terminate the policy control on the service of the user terminal.
A communication system consists of a user terminal, a service control server, and an AAA server. Upon user terminal authentication or information changes, the AAA server sends the user's information (including authorization data) to the corresponding service control server, which then manages policy for the user's service. The system includes an authentication server for the user terminal to authenticate with the AAA server, or authentication can occur through an operator. If using an authentication server, it determines its relationship with the service control server and relays its information during authentication. When the user terminal goes offline, the AAA server sends an offline instruction to the service control server, which stops policy enforcement. The user terminal comprises a processor and memory with instructions to authenticate with the AAA server.
9. The communication system according to claim 8 , wherein the authorization information of the user terminal comprises address information and/or identification information and/or service policy information of the user terminal.
The communication system, as described in the previous claim, utilizes user terminal authorization information including address information, identification information, and/or service policy information of the user terminal. This information is passed from the AAA server to the service control server upon authentication or user data change, enabling appropriate policy implementation.
10. The communication system according to claim 8 , wherein the service control server being configured to perform policy control on a service of the user terminal according to the user information comprises: the service control server issuing a user forwarding information table of the user terminal to a forwarding plane corresponding to the service control server according to the user information; wherein the service control server terminating the policy control on the service of the user terminal according to the user information comprises: the service control server deleting the user forwarding information table of the user terminal in the forwarding plane corresponding to the service control server.
Within the communication system as described in claim 8, the service control server manages policy by issuing a user forwarding information table to a forwarding plane based on user information received from the AAA server. When the user goes offline, policy termination involves the service control server deleting the user forwarding information table from the forwarding plane.
11. The communication system according to claim 8 , wherein the service control server is further configured to, after the policy control is performed on the service of the user terminal according to the user information, send a charging start instruction to the AAA server; and after the user offline instruction has been received, send a charging stop instruction to the AAA server.
This invention relates to a communication system for managing user services and charging processes. The system addresses the need for efficient policy control and charging coordination in communication networks, particularly when users connect or disconnect from services. The system includes a service control server that enforces policies based on user information, such as subscription details or service usage rules. After applying these policies to a user terminal's service, the server sends a charging start instruction to an Authentication, Authorization, and Accounting (AAA) server to initiate billing. When the user disconnects, the service control server receives an offline instruction and sends a charging stop instruction to the AAA server, ensuring accurate billing for the service duration. The AAA server handles authentication and accounting functions, while the service control server manages policy enforcement and charging coordination. This system improves service management by dynamically controlling access and billing based on user status, reducing errors in charging and enhancing service reliability.
